3.2.2 FAN Speed
Please check your motherboard to see how many Fan Headers
exist. Usually there will be one CPU Fan, one System Fan,
and/or one Power Fan available, depending on different
motherboard model. When the Fan is not connected or
doesn’t exist, the Fan Speed Column will be indicated by a
black-colored-character “OFF”.
Note: Only the fan with three output pins can be monitored!
• CPU FAN:
The CPU Fan and its heatsink assembly must be installed
directly on the top of CPU to keep it in normal temperature.
When the CPU Fan is running, the Fan Speed Column will
display the number of RPM in blue-colored-character among
the yellow-colored background. If it turns low speed or stops,
the fan speed column will be indicated by RPM in the same
blue-colored-character among the red-colored background.
Note: The CPU may be damaged or operate unstably if the
CPU Fan turns low speed or stops.
• SYS FAN:
The System Fan is usually installed in the chassis to keep the
system chassis in normal temperature.
When the System Fan is running, the Fan Speed Column will
display the number of RPM in blue-colored-character among
the yellow-colored background. If it turns low speed or stops,
the fan speed column will be indicated by RPM in the same
blue-colored-character among the red-colored background.
• NB FAN:
The NB (North Bridge) Fan is usually installed directly on the
top of the North Bridge Chipset to keep it in normal
temperature.
When the NB Fan is running, the Fan Speed Column will
display the number of RPM in blue-colored-character among
the yellow-colored background. If it turns low speed or stops,
the fan speed column will be indicated by RPM in the same
blue-colored-character among the red-colored background.
